After tragedy strikes, a grieving father discovers an ancient burial ground behind his home with the power to raise the dead.

Louis Creed, his wife Rachel, and their two children, Gage and Ellie, move to a rural home where they are welcomed and enlightened about the eerie 'Pet Sematary' located nearby. After the tragedy of their cat being killed by a truck, Louis resorts to burying it in the mysterious pet cemetery, which is definitely not as it seems, as it proves to the Creeds that sometimes, dead is better.

The Creeds have just moved to a new house in the countryside. Their house is perfect, except for two things: the semi-trailers that roar past on the narrow road, and the mysterious cemetery in the woods behind the house. The Creed's neighbours are reluctant to talk about the cemetery, and for good reason too.
